9)After all of the water has drained, replace the drain hose, drain plug, and drain clamp in their original positions.

10)Remove the bolts securing the lower housing to the gear motor. Lift the evaporator up slightly.

11)Remove the bolts securing the gear motor.

12)Disconnect the gear motor wires, then remove the gear motor.

13)Attach the spline coupling from the old gear motor to the new gear motor.

14)Install the new gear motor and reconnect the electrical wires.

15)Open the water supply line shut-off valve and check for water leaks.

16)Plug the unit into the electrical outlet, then move the power switch to the "ON" position.

17)Allow the icemaker to operate until the gear motor starts. Check for water leaks.

18)Move the power switch to the "OFF" position, then unplug the unit from the electrical outlet.

19)Replace the removed parts and panels in the reverse order of which they were removed.
